2. Description of the Related Art Generally, in an office machine, paper sheets for which recording and reproduction of data have been completed are discharged to a paper discharge tray, but the paper discharge operation is continued even when the paper discharge tray is full. In order to prevent the adverse effects of this, there is a paper discharge detection device that detects the amount of paper sheets in the paper discharge receiver.

An example thereof will be described below with reference to FIGS. 6 and 7. Although only one is shown in the figure, a discharge passage 101 is provided in the frame 100 facing each other. Although not shown, the paper discharge passage 101 guides the paper discharged from the printing device or the magnetic recording device, and the end portion of the paper discharge passage 101 is provided with two branch passages 102 whose discharge paths can be switched by a guide flap (not shown). , 103. Paper discharge rollers 104 and 105 are rotatably provided at the end of one branch path 102. Further, a paper discharge receiver 106 is rotatably held on the frame 100 about a support shaft 107, and a paper discharge guide plate 108 and a sensor plate 109 facing the paper discharge receiver 106 are fixed. . An actuator 110 formed of a leaf spring is held on the sensor plate 109 so as to be rotatable around a support shaft 111.
A micro switch 112 which is turned on and off by 0 is attached via a mounting plate 113. The actuator 110 is biased counterclockwise by a spring 114. Then, as shown in FIG. 7, the discharge guide plate 108 is formed with an opening 115 through which the tip of the actuator 110 is projected.

In such a conventional sheet discharge detecting device, the sheet S guided by the sheet discharge path 101 is discharged from the branch path 102 or 103 by the guide flap. When the paper sheet S is discharged from the branch path 102, the paper is sequentially discharged to the paper receiving tray 106 by the paper discharging rollers 104 and 105. When the number of sheets S in the sheet receiving tray 106 reaches a certain number, the actuator 110 rotates clockwise around the support shaft 111 against the urging force of the spring 114 to turn the microswitch 112 on and off. Switch. The detection signal of the micro switch 112 at this time warns the full state of the paper discharge tray 106 or prohibits data recording, reproduction, and paper discharge operations.

[0005]

The conventional paper discharge detection device shown in FIGS. 6 and 7 is only for the purpose of actuating the micro switch 112 when the paper sheet S in the paper discharge tray 106 is detected. Since the actuator 110 is independently provided in the above, there is a problem that the number of parts and the number of assembling steps increase.

Further, the ticket issuing machine body 2 is provided with a paper discharge tray 19 for storing the ticket S which is a paper sheet discharged from the branch path 9 of the paper discharge path 8. As shown in FIGS. 1 and 2, the discharge receiver 19 is in the form of a tray whose one surface is open, and is rotatably held about a support shaft 20. The paper discharge roller 18 is a paper discharge receiver 19
A roller 22 with a claw having a large number of feed claws 22a on the outer periphery is fixed to both sides of the discharge roller 18 on the drive side, which is located slightly above the bottom surface 21 of the.

A support shaft 24 is installed on a frame 23 which is opposed to each other and forms a part of the ticket issuing machine body 2. A synthetic resin discharge guide plate 25 is rotatably mounted on the support shaft 24. Held in. A plurality of ribs 26 that support one surface of the ticket S and a bulge portion 27 that has a smooth spherical surface and protrudes from the central portion toward the paper ejection receiver 19 are provided on the paper ejection guide plate 25.
